How to install dash on Linux Mint

dash

POSIX-compliant shell

The Debian Almquist Shell (dash) is a POSIX-compliant shell derived
from ash.
Since it executes scripts faster than bash, and has fewer library
dependencies (making it more robust against software or hardware
failures), it is used as the default system shell on Debian systems.

Enable snaps on Linux Mint and install dash

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.

Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.

Enable snapd

Snap is available for Linux Mint 18.2 (Sonya), Linux Mint 18.3 (Sylvia), and the latest releases, Linux Mint 19 (Tara) and Linux Mint 19.1 (Tessa).
You can find out which version of Linux Mint you’re running by opening System info from the Preferences menu. To install snap from the Software Manager application, search for snapd and click Install.

Alternatively, snapd can be installed from the command line:

Either restart your machine, or log out and in again, to complete the installation.
